KEY-RING.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed January 14, 1905. Serial No. 241,213.

To all zul/1,0m, 711,603/ concern:

Be it known that I, ARTHUR R. SEE, a citizen of the United States, residing at Alma, in the county of Marion and State of Illinois, have invented certain new and useful Improvements in Key-Rings, and I do declare the following tobe a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, Which form a part of this specification.

My invention relates to key-rings, and has for its object to provide a device of this class which is particularly simple in its construction, easy and cheap to manufacture, strong, durable, and efficient.

A further object of my invention is to provide a key-ring from which the keys may be quickly and easily attached and as easily and as quickly detached.

I/Vith these objects in view my invention consists in the novel construction of the keyring, and particularly in the construction providing for locking the same.

Referring to the accompanying drawings, Figure 1 is a perspective view of the key-ring in a locked or closed position. Fig. 2 is a view, partly in section, showing the construction of the two ends of the ring. Fig. 3 is a similar view showing the two ends disengaged or unlocked. Fig. 4 is a perspective view of one end of the ring, and Fig. 5 is a perspective view of the other end.

Like numerals of reference indicate the same parts throughout the several figures, in which- 1 indicates the key-ring, which is constructed of a suitable spring metal, said ring being provided with the half-round ends 2 and 3, the flat surfaces of the end portions being transverse of the ring, as shown in Figs. 2, 3, and 4. A portion of the metal at the end 2 is cut away, as shown, forming a shoulder 4 and a flat surface 5. A projection 6 is formed on the eXtreme end 2, and an opening or recess 7 is made in the shoulder 4, as shown.- A portionof the metal at the end 3 is cut away at 8, and a projecting point 9'is formed on the eXtreme end 3, a groove 10 eX- tending from the pointed projection 9 to the shoulder 10', Where a recess 11 is formed, as shown.

Having thus fully described my invention, its operation is as follows: As shown in Fig.

2, the projecting point 9 of the end 3 enters the opening or recess 7 in the shoulder 4 of the end 2, while the projection '6 of the end 2 enters the recess Il in the end 3, both ends 2 and 3 being sufliciently cut away, as shown, so that when the ring is in a locked position the entire ring is smooth, free of projections, and the metal around the entire ring of the same circumference. Referring to Fig. 3, the projection 6 is shown in the groove l0. order to unlockor disengage the ends of the ring in order to attach or detach a key, the

projection 6 is forced down out of the recess Il until it strikes the groove I0. The ring is then simply pulled open, the projection 6 following the groove l0 until the ends are pulled entirely apart. The key is then attached or detached and the projection 6 again placed in the groove l0 and the ends allowed to spring together into their locked position, as shown in Fig. 2, thegroove I0 guiding the projection 6 into the recess 11 and also guiding the pointed projection 9 into the l opening or recess 7.

Hav-ing thus fullydescribed my invention, I do not wish to be understood as limiting myself to the exact construction as herein set forth, as various slight changes may be made therein which would fall within the limit and scope of my invention, and I consider myself clearly entitled to all such changes and modifications.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is*

l.- A key-ring having one of its ends provided with a projection and an openingor recess, and its other end provided with a projection constructed to enter said opening or recess, and also provided with a groove and a recess constructed to. accommodate said firstmentioned projection, substantially as described.

2. A key-ring having overlapping end portions formed half round, a recess in each of said end portions, and a projection on each of said end portions arranged to enter the said recess in each overlapping portion, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.

ARTHUR R. SEE.
